The physically handicapped people need encouragement to perform as many activities as his/her physical limitations allow both at home and in the. community. Such encouragement combats the tendency of physically handicapped people to remain isolated. This encouragement may take many forms with one such form being the use of work simplification techniques and uncomplicated aides to assist physically handicapped people to perform different desired tasks, such as those managed by the use of the hands of a handicapped person. It is desired that devices be provided for assisting the physically handicapped persons to perform tasks that are managed by the use of their hands. It is further desired that storage means be provided for these devices which further assist the handicapped person by allowing easy accessibility of the devices by physically handicapped persons.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide for devices for assisting a physically handicapped person to perform tasks that are managed by the use of their hands.

Another object of the present invention is to provide devices that are easily held and gripped by the handicapped person.
It is still a further object of the present invention to provide for devices having quick-release mechanisms to allow for easy interchanging of holders adaptable for the instruments used to perform tasks by the handicapped persons.
In addition, it is an object of the present invention to provide for a storage box having a shelf that is form fitted for operatively cooperating with the quick-release mechanisms of the devices.
In accordance with these and other objects, the invention provides for a device for assisting a physically handicapped person to perform tasks that are managed by the use of their hands having digits. The device comprises a hollow member, first and second rings, an insert, and a holder. The hollow member has first and second ends and a central bore having predetermined dimensions and extending at least partially therethrough and encompassing the first end thereof The hollow member has a plurality of apertures having threads therein. The first and second rings are attached to the hollow member and are spaced apart from each other in a predetermined manner and each is dimensioned to receive one of the digits of the hand of a handicapped person. The insert has a threaded end for insertion into and threadedly engaged with anyone of the threaded apertures. The holder has first and second ends with the first end being dimensioned for insertion into the central bore by way of the first end of the hollow member and with the second end thereof having provisions for holding an instrument used in the performance of a task managed by the use of the hand of the handicapped person.
